Hello, I love my beautiful Supersport Performance 12 GA. What I don't love is that the extended chokes are coming loose. This is a pretty expensive gun to have such a critical flaw. I clean the threads and lube the chokes after each day at the range. However, they just do not hold. They are coming loose before I even finish a round of trap. NOT acceptable. I even use the choke tool, and tighten them down to a point where I feel if I add more torque, I may strip the threads. Again not acceptable. Other forums suggest using a heavy grease to help keep the tubes in place, rather than the lube that comes with the gun. All advice appreciated. Thanks.
